Abstract

An articulated vehicle is provided including a system for controlling the rate and stability of unloading of material supported by the articulated vehicle.

Claims

1. A transport vehicle configured to transport a load including:

a chassis;

a plurality of wheel assembles operably coupled to the chassis to provide rolling support for the chassis;

a load bin supported by the chassis and configured to support a load transported by the transport vehicle;

at least one load bin cylinder configured to move the load bin between raised and lowered positions; and

means for controlling the at least one load bin cylinder to optimize spreading of the load at a dump site.

2. The transport vehicle of claim 1, wherein the controlling means determines the speed of the vehicle to control the at least one load bin cylinder.

3. The transport vehicle of claim 2, wherein the controlling means includes a controller and a speedometer providing speed information to the controller.

4. The transport vehicle of claim 1 wherein the controlling means determines the material type to control the at least one load bin cylinder.

5. The transport vehicle of claim 4, wherein the controlling means includes a controller and a plurality a materials type selections providing an indication of the material type to the controller.

6. The transport vehicle of claim 1, wherein the controlling means determines the stability of the vehicle to control the at least one load bin cylinder.

7. The transport vehicle of claim 6, wherein the controlling means includes a controller and an inclinometer providing the angle of inclination of the vehicle to the controller to determine the stability of the vehicle.

8. The transport vehicle of claim 6, wherein the controlling means includes a controller and at least one load sensor providing weight information to the controller to determine the stability of the vehicle.

9. The transport vehicle of claim 1, wherein the controlling means determines the amount of material carried by the load bin to control the at least one load bin cylinder.

10. The transport vehicle of claim 9, wherein the controlling means includes a controller and at least one load sensor providing weight information to the controller to determine the amount of material carried by the load bin.

11. The transport vehicle of claim 1, wherein the controlling means includes an operator input to begin optimized spreading of the load.

12. The transport vehicle of claim 1, wherein the controlling means lowers the load bin after determining the angle of the load bin has reached a predetermined angle.

13. A transport vehicle configured to transport a load including:

a chassis;

a plurality of wheel assembles operably coupled to the chassis to provide rolling support for the chassis;

a load bin supported by the chassis and configured to support a load transported by the transport vehicle;

at least one load bin cylinder configured to move the load bin between raised and lowered positions; and

a controller receiving inputs including at least one of the vehicle speed, the vehicle inclination, the weight of the load supported by the load bin, and type of material supported by the load bin to control the position of the at least one load bin cylinder.

14. The transport vehicle of claim 13, wherein the controller increases the rate of raising of the load bin by the at least one load bin cylinder as the vehicle speed increase.

15. The transport vehicle of claim 13, wherein the controller raises load bin only when the vehicle inclination is below a predetermined angle.

16. The transport vehicle of claim 15, wherein the controller uses the vehicle inclination and weight of the material supported by the load bin to determine whether to raise the load bin.

17. The transport vehicle of claim 13, wherein the controller raises the load bin at a first rate based on a first type of material supported by the load bin and raises the load bin at a second rate based on a second type of material supported by the load bin, the first material being different than the second material and the second rate being slower than the first rate.

18. The transport vehicle of claim 13, wherein the controller determines the stability of the vehicle and only raises the load bin when the stability is above a predetermined level.

19. The transport vehicle of claim 13, wherein the controller determines the angle of the load bin.

20. The transport vehicle of claim 19, wherein the controller lowers the load bin after determining the angle of the load bin has reached a predetermined angle.
